The axilla is a region of the upper arm that extends from the shoulder to the elbow. It contains the brachial plexus, a network of blood vessels and nerves that supply the arm.
The brachial plexus is a collection of blood vessels and nerves that originate from the abdominal aorta and then divide into two branches, the internal and external brachial arteries. These branches run along the inner and outer surfaces of the upper arm, supplying the arm with blood and nutrients.
The internal brachial artery carries blood from the heart to the tissues of the upper arm, including the muscles, bones, and joints.
The external brachial artery carries blood from the heart to the skin, muscles, and nerves of the upper arm.
The axilla and brachial plexus are responsible for supplying the upper arm with blood and nutrients, and for carrying waste products away
